Antero Shares Tumble After Cutting Utica Gas Estimate

Shares of Antero Resources Corp., an oil and natural gas producer that began trading in October, fell the most ever after cutting its production estimate for a section of its Utica Shale holdings.

Antero dropped 6.6 percent to $59.06 at the close in New York. Prior to Monday, the shares had gained 44 percent since the Denver-based company’s public offering on Oct. 9.

Antero reduced its estimate for how much gas one section of its Utica holdings will yield by 34 percent, according to a statement. Another section’s production forecast was cut by 31 percent. The company’s oil and gas holdings are located in West Virginia, Ohio and Pennsylvania.

Antero has 12 buy recommendations and five holds from analysts, according to data compiled by Bloomberg. The company spent $2.1 billion to find and develop new fields in 2013 and has untapped reserves large enough to sustain output for four decades.
